Research Note


The myrtle rust pathogen, Austropuccinia psidii, was recently detected in New Zealand and Singapore. We used microsatellite markers to identify the strain of A. psidii that caused these incursions. Our results show that the pandemic strain of the pathogen caused outbreaks in both New Zealand and Singapore.
